Summary	0004393: SOGo generates load bursts with excessive CPU and RAM utilization
Description	Environment: Mail System for small business (5-10 users). HW: 8core Intel 2GHz (Mac mini 2011) Core: Postfix / Dovecot (from original repos) DB: PostgreSQL 9.5 Web/Calendar: SOGo 3.2.10 After a restart, the overall CPU utilization is around 1-2%, RAM around 1GB Over time, CPU utilization increases to a top of 60%. (physical) RAM increases to a utilization of up to 10 GB. top shows that there are 4-5 processes sogod that are responsibe for this work load.
Steps To Reproduce	Install and start SOGo on a 5 user serving Mail system. After restart: CPU 1-2%, RAM 1GB After 2h: CPU 5%, RAM 3GB After 6-8h: CPU pulses between 25-50% and RAM between 2-12GB Restart SOGo daemon and the phenomenon disappears immediately to reemerge after above described time.
Additional Information	Pulsing interval 30s (looks like a garbage collector is hitting in regularly) Growth in memory and CPU demand looks like a memory leak. This behaviour occured last December and got really observable at the beginning of 2018. Configuration was not altered since 2016.
